Exynos5: Config: Place environment at the end of SPI flash
Currently environment resides at the location where BL2 ends. This may hold good in case there is an empty space at this position. But what if this place already has a binary or is expected to have one. To avoid such scenarios it is better to save environment at the end of the flash.
